Safe Spaces for Women to be Physically Active in Greater Noida City, India

Neha J Pagidipati, Prasad Pathak, Shayna M Clancy, Gatha Sharma and Truls Ostbye

Abstract

Women in urban India have low levels of physical activity, and the lack of safe spaces to be physically active is likely an important factor. The objectives were to develop a spatial database of areas and facilities in order to assess conduciveness to physical activity in Greater Noida, to assess the safety and usability of roadways and community parks in this area.

Development of New Material Based on Polyvinyl Alcohol/Palm Kernel Shell Powder Biocomposites

Nur Fazreen Alias, Hanafi Ismail, Mohamad Kahar Ab Wahab, Santiagoo Ragunathan, Hosta Ardhyananta and Sam Sung Ting

Abstract

New biocomposite films from Polyvinyl alcohol (PVA)/Palm kernel shell powder (PKSP) were prepared by solution casting method. The effect of PKSP addition on the film was studied based on the tensile properties, physical properties and biodegradability. From tensile test, it was found that the tensile properties decreased with the increasing PKSP loading in the composition.

Assessment of 'Bacterial (Acidic)-Leaching' of Rare Earth Elements from a Phosphate Ore

S Hussien, P Patra, P Somasundaran and H El Shall

Abstract

Bioleaching methods are environmentally benign and economical options for extraction of rare earth elements (REEs) from low grade REE ores. We conducted shake-flask and column bio-leaching (Acidithiobacillus ferrooxidans) studies with a low grade phosphate ore constituting REEs, fluorapatite, and silicates.

Genotoxic Evidences of Glyphosate and Chlorpyriphos on Eisenia fetida Coelomocytes

Silvana Patricia Curieses, Maria Elena Saenz, Jose Luis Alberdi, Santiago Martinez, Marcelo L Larramendy and Walter Di Marzio

Abstract

The widely use of pesticides in modern agricultural enables increased crop yields. However, pesticides residues can contaminate agricultural and adjacent lands and become an ecotoxicological threat to non-target organisms, included humans.

Cyto and Genotoxicity of Positive and Negative Coated Silica Nanoparticles on Celomocytes of Earthworms Eisenia fetida (Oligochaeta, Annelida)

Di Marzio WD, Curieses S, Scodeller P, Alberdi JL and Saenz ME

Abstract

To understand and assess the effects of nanoparticles (NPs) on the environment, should be well established quantitatively the concentration-response relationships. Also relate the potential effects on selected variables of response with the exposure to sub-lethal levels of NPs. In this work, we describe the ecotoxicological evaluation of negative and positive coated silica NPs (Si-Nps) on coelomic cells from Eisenia fetida.

A Systems Approach to Near Surface Disposal Facility Design

Joseph H Rustick and James H Clarke

Abstract

A fundamental near-surface disposal challenge is the development and use of a risk-informed and performance-based decision tool that incorporates the impacts of waste, waste form and waste container-specific, facility design-specific and facility location-specific factors into the overall assessment of anticipated facility performance. This decision-making tool must have the ability to assess the influence of each disposal facility component on overall performance for specific wastes and disposal site environments.

An Overview of the Effects of Heavy Metals Content in Wastewater on Anammox Bacteria

Cherh Yih Mak, Jih-Gaw Lin and Mohammed JK Bashir

Abstract

The application of Anammox process in treating nitrogen rich wastewater had been more preferable since the discovery of Anammox process and Anammox bacteria at 1999 due to the advantages of energy saving and cost reduction compared to the conventional nitrification/denitrificationi process. However, often nitrogen-laden wastewater such as metal refinary wastewater, swine, industrial wastewater, and landfill leachate contain various concentrations of heavy metal ions such as Cadmium, Copper, Lead, Mercury, Nickel, Zinc, Silver and Ferrous iron.

Environmental Art and Environmental Beliefs: The Case of Plastic Bag Pollution in Oceans

Robert W Turner

Abstract

This paper reports the results of two experiments exploring the impact of exposure to environmental art on environmental beliefs, using images of plastic bag pollution in oceans. Even though the experimental design investigates only the immediate impact of a brief exposure to artistic images, the design controls well for other factors that might influence changes in environmental beliefs.

Temporal Variation of Nitrogen and Phosphorus Species Distribution on Total Phytoplankton Biomass in Eutrophic Lakes

Anusha Balangoda

Abstract

To aid in the eutrophication management, the relationships between total algal biomass in response to varying nitrogen and phosphorus species concentrations, Volatile (VSS), and Total Suspended (TSS) solids in the water column were investigated.

Landslide Effect on an Oribatid-Mite Community in a Monsoon Forest

Hao-Chiang Chien, Ping-Chun Lucy Hou, Haggai Wasserstrom and Yosef Steinberger

Abstract

Landslide-caused erosion of soil alters above ground plant cover and primary production, and is a major disturbance in forests and agro ecosystems in Taiwan. Bimonthly litter collections were conducted for one year, with oribatid mites studied at landslide sites and on the undisturbed forest floor.

Soil Ozonation for Nematode Disinfestation as an Alternative to Methyl Bromide and Nematicides

Nahed Msayleb, Ramesh Kanwar, Huaiqing Wu and J (Hans) van Leeuwen

Abstract

Phytoparasitic nematodes are important pests that cause severe crop yield losses. In the past, methyl bromide and other proprietary nematicides have been used as management practices, but these practices are unsustainable and lead to atmospheric pollution and ozone layer destruction.

Ozonation Efficacy in the Treatment of Soil-Borne Phytophthora sojae in Cultivating Soybeans

Nahed Msayleb, Ramesh Kanwar, Huaiqing Wu and J (Hans) van Leeuwen

Abstract

Ozonation was studied for inactivating Phytophthora sojae, a predominant soybean pathogen that causes root and stem rot, and pre-and post-emergence soybean damping-off. Typically, fungicides are used to treat soils to control the damage from P. sojae to soybean production.
